LOS ANGELES – On the eve of its announcement of board election results, the Screen Actors Guild says 87 percent of its members support holding out for a better contract from Hollywood studios.

The studios called the guild’s survey flawed.

Guild President Alan Rosenberg said Wednesday that results of a mail-in survey justified the union’s rejection of the studios’ final offer for a contract covering film and prime-time TV productions.

Actors have continued to work under the terms of a contract that expired June 30.

The Alliance of Motion Picture and Television Producers said the union’s 12 pages of information accompanying the survey were “hopelessly one-sided” and said the studios’ final offer remained on the table.

On Thursday, the guild is to announce the results of an election that could give an upstart group control of the guild’s national board.
